Scientific paper

A total of 21 and 14 stars in the fields of the open clusters Tr 15 and Tr 14, respectively, have been observed in order to provide spectral types derived through the MK process. The spectroscopic parallaxes for those groups have also been obtained, finding that Tr 15 is almost at the same distance from the sun as Tr 16 but that Tr 14 is possibly more distant. This cluster, with its high concentration of O-type stars, is also the youngest of both groups studied in this work and may be younger than Tr 16.
